Has called my (silent) landline consecutively for several days, I answer to silence, then one of us hangs up.
Dialed number back on different silent phone number, to hear recorded message "There are no active phone calls to monitor."

annoying calls both mobile and landline.

This number has called me every day for the past month. I have called the number back and a recorded message plays 'There are no active calls to monitor'

Keeps ringing throughout the day while I'm at work. Even rang at 8pm in the evening. I'm not answering it as I don't know who it is and they won't leave a message. Pain in the butt

A call-centre of some kind.

This number is harrassing me. 3 times a day !! Cant lodge complaint with do not call register as they never say anything so dont know name.
Next time they ring they are in for a surprise!

This number calls me at least once a day Monday to Friday. I no longer answer any (02) numbers because I am being pestered by charities who call from NSW also on a regular basis. When I did answer early on in the piece I would often just get complete silence - then disconnected.

Have been receiving several calls each day for the past 3 days. I am in Brisbane, don't know why a Sydney number is phoning so I don't answer, if you don't leave a message I will not phone back.

Have called me 3 times in two days (2 missed calls). I answered once to stunned silence...I called back once to get a recorded message...wtf?

They rang me ,
I answered ,
the woman sounded far away and she couldn't hear me and she hung up after less than a minute.

Missed the call and called back. It rang once then an English accented recorded message said "There are no active calls to monitor" and it hung up.
